Drinkng problems

Thing to remember is an alcoholic can stop drinking, they have to want to. A friend in AZ is a recovering Alcoholic/Addict. He lost everything. Wife & son left in the middle of the night, have not been heard form since. Woke up in a cardboard box in Vegas and decided enough is enough. Has not had a drink or used drugs in close to thirty years. And is very up front about it all. When I lived there we would often meet in a bar. He would always have a six pack in the fridge for when his friends that could drink showed up. Other have said that if you have nothing invested just to walk away. Thing is, if you do and she decides to change she very well could be the nicest person you ever meet...
